On robust asymmetric equilibria in asymmetric R&D-driven growth economies

  • Paolo Giordani


  • Luca Zamparelli


In an R&D-driven growth model with asymmetric fundamentals the steady state equilibrium R&D investments are industry-specific and they are such that R&D returns are equalized across industries. Return equalization, however, makes investors indifferent as to where to target research and, hence, the problem of allocation of R&D investments across industries is indeterminate. Agents' indifference creates an ambiguous investment scenario. We assume that agents hold "ambiguous" beliefs on the per-industry profitability of their R&D investments. Investors' aversion towards ambiguity (in the sense of Gilboa-Schmeidler, 1989) eliminates the indeterminacy of the R&D investment problem. In particular, we prove that the asymmetric return-equalizing equilibrium is robust against a however small degree of investors' aversion to ambiguity.
